I stayed at Hard Rock but the machines were so bad I took a cab across town to river spirit. Although the machines here hit better and I won over 1000 dollars, the management and security were extremely rude. The late night food is very poor and unhealthy. The smoking in the casino is absolutely terrible and the non smoking areas are right next to them. The buffet was ok the next day but really for lunch felt more like Golden corral. Not the greatest casino not the worst. In Tulsa i found it to be the best one.
Also please note, the Indian casinos are not regulated at all except by themselves. They do not have a minimum payout and it shows.
